/**
 * 使用RabbitMQ
 * 1、引入amqp场景：RabbitAutoConfiguration就会自动生效
 * 2、给容器中自动配置了
 * RabbitTemplate,AmqpAdmin,CachingConnectionFactory,RabbitMessagingTemplate;
 * 所有的属性都是spring.rabbitmq
 *
 * @ConfigurationProperties(prefix = "spring.rabbitmq")
 * public class RabbitProperties
 * <p>
 * 3、给配置文件中配置  spring.rabbitmq信息
 * 4、@EnableRabbit:@EnableXxxxx;   开启功能
 * 5、监听消息：使用@RabbitListener；必须有@EnableRabbit
 *      @RabbitListener:    类+方法上(监听哪些队列即可)
 * @RabbitHandler:标在方法上（重载区分不同的消息）
